Answer:

see explanation

Step-by-step explanation:

1

2(3x + 1) = 4(x + 2) ← distribute parenthesis on both sides

6x + 2 = 4x + 8 ( subtract 4x from both sides )

2x + 2 = 8 ( subtract 2 from both sides )

2x = 6 ( divide both sides by 2 )

x = 3

------------------------------------------------------------

2

6x = 4(x - 3) ← distribute parenthesis

6x = 4x - 12 ( subtract 4x from both sides )

2x = - 12 ( divide both sides by 2 )

x = - 6

-----------------------------------------------------------

3

2(4x + 7) = 4x + 30 ← distribute parenthesis on left side

8x + 14 = 4x + 30 (subtract 4x from both sides )

4x + 14 = 30 ( subtract 14 from both sides )

4x = 16 ( divide both sides by 4 )

x = 4

---------------------------------------------------------------------

4

50 = - (y + 22) ← distribute parenthesis by - 1

50 = - y - 22 ( add 22 to both sides )

72 = - y ( multiply both sides by - 1 )

- 72 = y , that is

y = - 72

Find the exact or approximate area of the shaded region
Lana71 [14]

Answer: 18.24 cm^2

Step-by-step explanation:

the two 135 degree angles indicate that the third angle (the one with the shaded region) is 90 degrees, which means that the shaded region is within 1/4 of the circle.

1. In order to find the area for that 1/4 region, you would have to find the area of the circle and divide it by 12

[r^2(3.14)]/4      pi is substituted by 3.14, and the radius is 8.

50.24 is the area of 1/4 of the circle.

2. Next you'd have to find the area of the triangle formed by the shaded region, and subtract the triangle from the area of the 1/4 circle.

the triangle is an isoceles triangle with two sides each valuing at 8cm, so to find the area of the triangle you would multiply the two sides (or square them since they're the same number) and divide by two

this means the triangle is 32 cm^2

3. we can subtract the 1/4 circle (50.24) by the area of the triangle (32) to get the area of the shaded region, which is <u>18.24 cm^2</u>

What is 6 1/3 - 4 2/3 = ?
kenny6666 [7]

Answer:

3 1/4 + 2 1/3 = 67 / 12 = 57 1/2

Step-by-step explanation:

Conversion a mixed number to a improper fraction: 3 1/4 = 3 · 4 + 1

4

= 13

4

Conversion a mixed number to a improper fraction: 2 1/3 = 2 · 3 + 1

3

= 7

3

Add: 13

4

+ 7

3

= 13 · 3

4 · 3

+ 7 · 4

3 · 4

= 39

12

+ 28

12

= 39 + 28

12

= 67

The length and width of a rectangle are
uysha [10]

Answer:

y=6

Step-by-step explanation:

(2y-3)*2=4y-6

You multiply by two because there are two sides that are considered the length

y+1*2=2y+2

Same thing here

4y-6+2y+2=32

6y-4=32

+4. +4

6y=36

/6 /6

y=6
